我可以在代码隐藏中获得样式的关键吗？(WPF)

   <Style x:Key="MyButtonStyle" TargetType="{x:Type Button}">
       <Setter Property="Background" Value="Red" />
       <Setter Property="Foreground" Value="White" />
    </Style>
</Window.Resources>

Style myButtonStyle = (Style)FindResource("MyButtonStyle");

Button myButton = new Button();
myButton.Style = myButtonStyle;
